This paper presents a design and analysis of microstrip antenna operating in Terahertz frequency band with dumbbell slots cut on the ground. Compactness and gain of the micro antenna has been considered as a design requirement. The performance of the antenna has been explored for Wireless Body Area Networks for measuring and monitoring various physiological parameters and sensors that help in overall monitoring of the health status of an individual. The dimensions of the antenna are264x400 μm operating at a frequency of 0.23THz. The performance of antenna has been observed for different substrates at mentioned frequency spectrum and the various parameters such as gain and return loss have been determined. The antenna has been simulated and the results have been calculated using Computer Simulation Technology (CST) Microwave Studio. The simulations have been successfully performed at lower Terahertz frequency range. The antenna designs have been optimized by implementing Artificial Neural Networks (ANN) using MATLAB. The best substrate for designing antenna and best value of gain was obtained corresponding to the minimum error value. The final designed antenna exhibits a return loss of -52.46 dB, gain 11.97 dB and final antenna has been designed with substrate Duroid 3210, operating at a frequency of 0.23 THz.
